It is very rare to find a teadust-glazed vase in this unusual shape, although variations of this vase are known. Examples in this shape with the sharply angled shoulders, are more often applied with ge-type glazes, such as the vase sold in London, 17 December 1996, lot 139.
The closest teadust-glazed comparisons to the present lot are the hexagonal hu-shaped vases with angled shoulders, one from the Hall Family Collection, exhibited at the Oriental Ceramic Society, Iron in the Fire, Ashmolean Museum, Oxford, 1988, illustrated in the Catalogue, no. 89, and on the cover; and another illustrated in Chinese Ceramics in the Idemitsu Collection, Tokyo, 1997, no. 965.
